Figure 7. Transmission electron micrographs of extracted plastoglobules of WT and fbn4 KD apple tree leaves.

Leaves were harvested from 4 to 5 month-old trees grown under 90 µE m⁻² s⁻¹ light intensity with a 12 h photoperiod. Extracted plastoglobules were stained with OsO₄ and observed on a copper mesh support. Transmission electron micrographs of electron opaque (black) and electron transparent (white) plastoglobules extracted from WT (upper row) and fbn4 KD (lower row) are shown.
